The lighting system for each illumination lamp of a vehicle such as an automobile or a motorcycle is usually a system in which a small lamp such as a sign (display) lamp and a headlamp are turned on in a stepwise manner using a lamp switch. That is, when the lamp switch is operated for the first time, the small lamps are turned on at the same time as the tail lamps, etc., and when the lamp switch is then operated again, the head lamps, fog lamps, etc. are turned on. Although filament light bulbs with good luminous flux rise characteristics are generally used as headlamps, the use of discharge lamps is also being considered in some cases.
しかしながら、上記のように前照ランプに放電

た。
However, when a discharge lamp is used as a headlamp as described above, the luminous flux is insufficient immediately after the headlamp starts (cold start), and it takes several tens of seconds to reach the rated value. When restarting before the lamp temperature drops, use a high voltage restart (hot start) of about 10KV to 20KV.
The problem was that it was necessary and dangerous.

するものである。 The present invention has been made in view of these problems, and provides a discharge lamp lighting system for a vehicle in which a sufficient luminous flux of the headlamp can be obtained immediately after the lamp switch is operated, and there is no need for high-voltage restart. It provides:

The discharge lighting system for a vehicle according to the present invention is provided with dimming lighting means for lighting the discharge lamp headlamp in a dimmed manner, so that the discharge lamp headlamp is lit in a dimmed manner when the small lamp is lit.

In the discharge lamp lighting system for a vehicle according to the present invention, the discharge lamp headlamp is turned on at a reduced level at the same time as the small lamp is turned on. In this state, if the lamp switch is operated to turn on the discharge lamp headlamp at its rated value, sufficient luminous flux will be immediately obtained. Furthermore, even if the lamp is switched from rated lighting to dimmed lighting, the lamp will not turn off, so there is no need for a high-voltage restart.

FIG. 1 is a circuit diagram showing one embodiment of the present invention. In the figure, 1 is a vehicle battery, 2 is a discharge lamp headlamp such as a headlamp, and 3 is a lighting power source for lighting the headlamp 2, which is comprised of a transformer, an inverter, and the like. Reference numeral 4 denotes an inductance element provided as dimming lighting means for lighting the discharge lamp headlamp 2 in a dimmed manner, and is interposed between the headlamp 2 and the lighting power source 3.
5a and 5b are switches that turn on a small lamp 6 such as a marker lamp and a discharge lamp headlamp 2 in stages, and both are configured as an integrated lamp switch, and the first operation turns on the switch 5a, and the next Switch 5b is turned on by operating .

ツチ操作後直ちに十分な光束が得られる。 When the switch 5a is turned ON, power is supplied from the battery 1 to the lighting power supply 3, and small lamps 6 such as each sign (display) lamp and tail lamp
lights up. At the same time, power is also supplied from the lighting power supply 3 to the discharge lamp headlamp 2 through the inductance element 4, and the discharge lamp headlamp 2 is turned on.
At this time, the current of the discharge lamp headlamp 2 is limited by the inductance element 4, so that the discharge lamp headlamp 2 enters a dimmed lighting state. Next, switch 5b is turned ON in this state.
When this happens, both ends of the inductance element 4 become short-circuited, and the rated current flows through the discharge lamp headlamp 2, resulting in the rated lighting state. At this time, since the tube temperature and electrode temperature of the discharge lamp headlamp 2 have increased due to the previous dimming lighting, the start-up characteristics are good and sufficient luminous flux can be obtained immediately after the lamp switch is operated.

要なく、そのままスイツチ５ｂをONにすれば良
く、安全である。 Furthermore, when switching from the rated lighting state of the discharge lamp headlamp 2 to the lighting of only the small lamp 6, the switch 5b is turned off, but since the inductance element 4 is connected, the discharge lamp headlamp 2 cannot be turned off. Then, the light goes into a dimmed lighting state again. Therefore, when restarting for rated lighting, there is no need for high voltage starting, and it is safe to just turn on the switch 5b.

When the switch 5a is turned on at T1 , the small lamp 6 is turned on and at the same time the headlamp 2 is turned on in a dimmed manner. In this state, when the switch 5b is turned on at time T2 , the small lamp 6 remains lit and the headlamp 2 lights up at its rated value. Next, when the switch 5b is turned off at time T3 , the headlamp 2 returns to the dimmed lighting state. Then, at time T 4 , switch 5
When a is turned off, the headlamp 2 as well as the small lamp 6 are turned off.

を点灯することができる。 In this way, while the small lamp 6 is lit, the discharge lamp headlamp 2 is also kept lit below its rated value, so that the start-up characteristics after the lamp switch is operated are good, and sufficient power is supplied immediately after the switch is operated. A luminous flux is obtained. That is, when driving at night when the headlamp 2 is required, generally even if the headlamp 2 is turned off, the small lamp 6 is almost never turned off, and if the small lamp 6 is turned on, the luminous flux rises quickly. Headlight lamp 2
can be lit.

By using the small lamp interlocking dimming method as in this embodiment, it is possible to improve the rise of the luminous flux with approximately the same space and cost as the conventional method.

As described above, according to the present invention, a means for dimming and lighting the discharge lamp headlamp is provided, and the discharge lamp headlamp is dimmed and lit when the small lamp is lit. A sufficient luminous flux of the illumination lamp can be obtained, and there is no need for high-voltage restart, which is advantageous in that it is safe.
